The Book of Mormon, the 2011 Tony winner for Best Musical, will open the 66th Annual Tony Awards.

Cast members, dressed as Mormons, will perform the hit musical's opening number, "Hello!," as they proceed from dressing room to dressing room until they arrive at the dressing-room door of Tony host Neil Patrick Harris, according to the New York Post. The Mormon offering will segue into a medley from classic Broadway musicals.

"South Park" creators-writers Trey Parker and Matt Stone, and Tony-winning Avenue Q songwriter Robert Lopez collaborated on the script and score to Mormon, which earned Tony Awards for Best Book, Best Score and Best Musical.
